# Feature: #98957 - Respect write-protected settings.php in Install Tool

See [forge#98957](https://forge.typo3.org/issues/98957)

## Description

The **Admin Tools > Settings** backend module now informs a system
maintainer if the `system/settings.php` file is write-protected.

This allows to make the settings file read-only after deployments.

## Impact

An info box is rendered in the module and each submodule, informing the system
maintainer that the `system/settings.php` file is write-protected.
In that case, all input fields are disabled and the submit buttons are not
available.
